It is a ready known in cutting glass tubes to utilize hot cutting methods, with or without a mark previously made with a steel cutter or a diamond; nevertheless in the caseof large diameters of 40 mm. and over, it is preferable, in order to obtain a clean cut to scratch the wall intern-ally with a diamond before effectin the heating. In order to do this a smal diamond set in a metal holder fixed to the end of a rod. is employed; the diameter of this rod should e such as to permit of introducing it into the glam tube in such a manner as to, reach the point at which the cut is tobe made. By then heating with the very pointed flame of a blowplpe the outer mark or the outerand inner marks made on the glass wall, the scratch is converted into a. crack. If care be had toimpart a movement of rotation 'to the tube, the crack extends along the heated portion whereby the wall If the tube rotates about its axis, the blowpipe remaining stationary, and if the scratch is wholly situated in. a plane per endicular to the said axis, the section will e straight; in the contrary case, the section may be elliptical The present invention has for its object to provide a single or multiple machine for carrying into practice the process set .forth above for cutting electric. incandescent lamps for the pur ose of removing the filament. The lamp is suspended and centered u on a support by means of two sleeves e ecting automatic andeoncentric clamping and which receive a movement of rotation about their common axis, in such a manner that the bulb can be displaced an ularly relatively to a diamond 'dl fix upon the machine and to a nozz e or the ingection of the heating or coolin agent.

trio clamping and which may or may not itself be clamped y a centering and fixing sleeve, is received in a support or in a claw; this support being carried by a verticalshaft, whose axis is in line with that oi the bulb and partici ates in the movement of displacement t at this latter receives. With the object of ermitting of accurately and instantaneously fixing and centering the bulb in the sleeves serving to impart to thema movement of rotation around its axis, the

sleeves are constructed upon the principleof the iris shutters wel known in photography. Each of the sleeves is constituted by two superposed rin adapted to be displaced 'angul'arly relativ y to each other and which have curved arms between them.

These arms, which are equal, are pivoted to one of the rm and act in combination with grooves therein; they are united by means of fingers upon their opposite extremities in such a manner that normally and under the producing their maximum angular separatlon, the arms intersect across the rings and symmetrically relatively to the axis around which the latter rotate. It will be understood that, in

these conditions, any body of revolution arranged between the arms will be clam ed by them and at the same time center relatively to the axis around which it is intended to be rotated by the system supporting it.

The invention is illustrated by way of ex ample in the accompanying drawing, in

which:

Figure '1 is a vertical section of a semiautomatic head for a machine embodying the invention, Fig. 1 is a detail view.

Fig. 2 is a corresponding plan,

Fig. 3 shows respectively H1 vertical sec' tion and in plan, in the closed position, the automatic clampin arms which enable the bulbsto be clamp and rotated in front of the diamond and the nozzle for the injection of the hot gas or current of cold air.

Fig. 4 is a vertical section showing a modified form of the semi-automatic head of the machine. p Broadly speaking each head is constituted by a frame 1 which, by mea'ns of vertical pillars 2 carries a support 3. This support jwhich 'is recessed centrally serves as a guide bearing for a central socket 4 rotatin on his rin meshes with a pinion 6 upon a verf faces of the support 3, the central socket 4 carries automatic clamping sleeves 8, 9 tending to fix the bulb in such a manner that its axis coincides with the axis of rotation of the whole constituted by the socket 4 and the clamping sleeves 8, 9 carried by the latter.

The automatic cIam, ing. sleeves 8, 9 (Figs. 3 and 4), resem' le shutters of the iris type as employed in'photography, and comprise rings 10 which are fixed upon the upper and lower faces of the movable socket 4. These rings receive respectivel nular metal cup 11 which is hel by the u rights 12 and the washers 13 but which ,is a a ted for angular displacement relatively to t e corresponding sup orting ringlOby sliding between the suite ly shaped aces of the said uprights 12. Are shaped metal armsl are housed in the cup 11-; these arms are similar and are fixed tolthe bottom. of the cup by means of pivot pins 15. At their opposlteextremit'ies the metal arms 14 have fingers 16 which enter guide slots 17 formed in the ring 10 of the sleeve. Asthe arms I 14 are of the same length, their pivotpins 15 and the guide slots 17 in which the fingers 16 upon them enga e are located at equal distances one from t e other, both uponthc bottom of the cup 11 in which they are housed and in the ring 10. The .cup 11, which is capable of angular displacement relatively to the ring 10 which isfastenerl to the'socket 4 (which asalready stated is given-a continuous movement of rotation aroundfits axis) is subjected to the action of a counter spring18 which is connected to the said rin 10 in such a manner that the arm 1.4- are isplaced and'intersect symmet= rically in the aperture of the central socket 4. By the manipulation of a knob 19 with which the cups 11 are provided, it is possi ble, owing tothe relative angular displace-- ment imparted to them, to cause the arms It to a pproach"or. recede from "each other;

owing to the ,fact that their .pivots 15 are integral with the movable cup-11 and that they k oscillate in such a manner as to assu'me a position at variable distances. from the general axis of rotation of the system,

' these-arms are displaced by'the engagement 1 of the fingers'16 on their opposite extremities in the slots 17 in the ring 10." When the knobs 19 are releasedilthe springs 18 act to return the cups to t eir original position and'the arms 14approachthe axis in such am'anner as to clamp. the object that has been arranged between them and center it, because they all receive, the same displacement relatively'to the axis. Beneath the assemblage of the movable socket 4 which produces the rotation of its two concentric s eeves 8, 9 there 'is'arranged in the axis defined by the uniform clamping ofthesesleeves,avert1calshaft20which asses through the frame 1. This shaft receives a socket21 the height of which is adjustable at willanditisitselffixed by means of a resilient feather 22 in a tubular sleeve 23 which bears,

In these conditions it will be noted that "by acting upon the knobs 19'of the concentric sleeves 8, 9 it is possible to displace the arms 14 in such a manner as to free the central aperture of't'ne socket 4 for the insertion of a lam therein. On releasing the knobs 19 the sprm 18 again close the arms 14 and center an lock the lamp inclosed therein. The lamp is'thus suspended beneath the socket 4: which it causes to rotate about its axis; the base of the lamp being engaged in the lower cup 21 which participates in the same angular displacement It will be noted that the lamp which thus rot-ates around its axis" of symmetry is accessible, throughout its entire periphery, be-

neath the upper support 3'to which it is pendent, in such a manner that there is no obstacle to the arrangement upon the frame 1 of the devices for cutting the Wall of the bulb. The frame 1 comprises two hollow uprights 27 in which two rods 28 are adapted to be displaced and fixed at an appropriate height.- These rods 28, "which are l united by a stay 29', Whose central port-ion embraces the shaft 20,.- respectively car the diamondholder 29 which is thus rigidly fixed and a nozzle'BO whose flattened nose 1 is adapted to embrace a portion of the eriphezycf the lamp. The aperture in t is nose renders it possible to project upon the wall a thin layer of hot gases or of cold air in such amanner as to crack the lass bulb and separateit into two arts. bviously the nozzle and the diamon holder might be fixed to the rods 28 in such a manner as to be displaced horizontally .or given any direction desired'relatively to the bulb.

As the sleeves 8, 9move in parallel planes every point of the wall. descrlbes a circumference in front ofthe spring pressed diamond '29 on the one hand and in .front of the slot in the nozzle 30 on the other hand. In these'conditionswhen, owing to the displacement of the bulb at an appropriate speed the diamond has traced a crrcumfer: ence upon the wall of the bulb, it is, only necessary to render operative a blow pipe 31 .which injects throughv the nozzle 30 a jet of hot air which cuts thebulb into two parts in accordance with the scratch made by the diamond, because the negates: the diamond is exactly the same as tliat of theslot in the said nozzle 30. It isthen possible, if

, merely by exerting traction upon-it.

It is then only necessary to arrange a second bulb in the sleeves S, 9 in order to sever it in the manner already described. When the bulbs severed in the manner described have been heated in such a manner as to burn the carbonaceous deposit which rendered them obscure and after the filament has been repaired or replaced, it is only necessary to bring together the constituent parts of the bulbs and uniteithem under the action of the flame of a suitable blowpipe, thereby reconstituting the lamps. In again producin a vacuum by known means a regenerate lamp is'obtained which can be utilized as 'a'new lamp.

It is obvious that in practice amachine would be provided with a number of heads adapted for rotation about a vertical shaft. In this manner an operative would be constantly employed in fitting lamps into the heads presentin themselves in front of her.

Inthe examp e illustrated in Fig. 2 a portion of a machine comprisin six heads has been shown. The frames 1 o the heads rest by means of bosses upon a ring 32 united by arms 33 to a hub 34, the uprights 2 insure the fixing of the heads 1 upon the ring 32 and pass through the'bosses with which the frames. are provided in the manner indicated. The hub 34 is uided hv a,hollow central shaft 35 which is utilized as a protectin -sheath for the conduits 36 conducting t e heatin or cooling agent to the branches 3? of t e blowpipes or injectors 31 in front of whose. orifices the nozzles 30 of each head present themselves in succession.

This sheath 35, which carries the branches 37, is also adapted to beraised or lowered at will by means of a counterweightedlever 38 which acts upon the whole by the jointed rod transmission 39 (see detail view Fig. 1"). The sleeve 35 has -carried upon it a boss mountedupon the rod 52 which at the opposite end is carried by the sliding.

sleeve 51 to which'm'ovement is lmparfed by the lever 38 through the links 39. y

The hub 34 carrying the driving ring 32 runs." by means ofa ball race upon the face of a boss 40 provided at the center of a plate 41. This plate, which serves as a base for the machine and which can be provided with supporting feet .carries the transmission actuating the system and also stop,

' sponding roller 26 driving the shafts 20 position. object, tap ets 42 are arranged beneath the ring an are adapted to engage in succession with a resilient bolt 43 serving as a stop. This bolt is carried by a hollow vertical sleeve 44' fixed to and the assemblage of automatic centering sleeves 8, -9 which hold the lamps. The spindles of the rollers 45 are arranged in sleeves 46 which are pivoted upon arms 47 belonging to thefixed table-l1. This sleeve 46 is subjected to the action of a spring 48 which tends to engage the corresponding roller 45 with the roller26 of the head l of the machine. The displacement in this direction is limited by a stop screw 49. The roller 45 receives its movement from the pulley 50 through a belt. Three driving rollers 45 may advantageously be provided for each movable head 1 in suitable positions to insure that the roller 26 of the head shall always be driven whatever disturbance maybe experienced in the position defined by the sto s 42 in combination with the bolt 43.

t is obvious that the lamp might be arranged inverted in the concentric clamping sleeves 8, 9 which insure its fixing and its centering relatively 'to the axis around which it is displaced. Thus, for example, the bulb might be fitted with its base body and cause it to participate in the gen the lower part ofthe lamp oral driving movement. The arran mantis for insuring the severing of the wal of the bulb and its so aration into two arts of course remain i entical with those escribed in the embodiment of the invention herein: before described" above.
